Problems solved by technology

[0002] In the prior art, the power supply charges the battery through a voltage conversion circuit. The power supply can be a photovoltaic module or a vehicle power supply. Since the voltage conversion circuit is a bidirectional circuit, the current can flow from the power supply to the battery, or from the battery to the power supply. During the charging process of the battery, the output voltage of the photovoltaic module will be unstable due to the instability of the light. When the output voltage of the photovoltaic module is converted by the voltage conversion circuit and the output voltage of the voltage conversion circuit is lower than the voltage of the battery, a backflow current will be generated. , that is, the current flows from the battery to the photovoltaic module, which wastes battery power and also causes unnecessary damage to the power supply

Abstract

The invention discloses a direct current charging control device of a mobile power supply and a direct current charging device of the mobile power supply, and the direct current charging control device of the mobile power supply comprises a voltage conversion module, a current detection module and a processing module, and the processing module is used for controlling the voltage conversion module to convert the voltage output by the power supply and then charge the battery, and controlling the voltage conversion module to stop working when the current is smaller than a preset current threshold so as to control the charging time and save electric energy. When backward current is generated, the result output by the current detection module to the processing module is that the current is zero, the current is smaller than a preset current threshold value at the moment, and the processing module still controls the voltage conversion module to stop working. The charging time can be controlled, the current of the battery can be prevented from flowing to the power supply to generate backward current, and the power supply is protected from being damaged.
